   Beispiels. 



     Brsetzt man das Isopren in   Beispiel 2 durch 500 Teile lethylbutadien und den   Hamster   durch 5 bis 10 Teile Thioharnstoff, so resultiert der entsprechende isomere Kautschuk. 



   Beispiele. 



   500 Teile einer Mischung aus gleichen Teilen ss-y-Dimethylbutadien und Isopren werden mit 5 bis 10 Teilen sterilisierten Blutserums versetzt. Nach mehrmonatlichen Stehen des Gemisches im Dunkeln resultiert eine weisse Kautschuksubstanz mit vorzüglichen Eigenschaften. 



   Beispiel 5. 



   Verwendet man an Stelle der in Beispiel 4 angegebenen Menge Isopren 500 Teile   jy-Dimethylbutadien   und fügt an Stelle des Serums 5 bis 10 Teile Hühnereigelb oder   Hühnerei-   weiss hinzu und lässt gleichfalls längere Zeit stehen, so findet auch hier die Polymerisation zu   Methylkautschuk   statt. 



   An Stelle der in den Beispielen genannten Butadiene können auch andere homologe oder analoge Butadiene, wie z. B.   at-Phenyl-y-methyl-,     &alpha;-&alpha;-Dimethyl-, ss-Propyl-, ss-Isobutylbutadien   oder ein   BRtadienderivat von   der Formel : 
 EMI2.1 
 oder andere Butadiene des genannten Typus Verwendung finden. 



   Erwärmt man die Reaktionsmassen, so wird der Prozess der   Polymerisation natürlich   erheblich beschleunigt.

   Example.



     If the isoprene in Example 2 is replaced by 500 parts of ethylbutadiene and the hamster by 5 to 10 parts of thiourea, the result is the corresponding isomeric rubber.



   Examples.



   500 parts of a mixture of equal parts of γ-dimethylbutadiene and isoprene are mixed with 5 to 10 parts of sterilized blood serum. After standing for several months in the dark, the mixture results in a white rubber substance with excellent properties.



   Example 5.



   If, instead of the amount of isoprene given in Example 4, 500 parts of γ-dimethylbutadiene are used and 5 to 10 parts of hen's egg yolk or hen's egg white are added in place of the serum and also left to stand for a long time, polymerization to methyl rubber takes place here too.



   Instead of the butadienes mentioned in the examples, other homologous or analogous butadienes, such as. B. at-phenyl-γ-methyl-, α-α-dimethyl, ß-propyl, ß-isobutylbutadiene or a BRtadiene derivative of the formula:
 EMI2.1
 or other butadienes of the type mentioned are used.



   If the reaction masses are heated, the polymerization process is of course considerably accelerated.
